Condensor fan help

Hey guys and gals been awhile since ive posted. Ive gotta 012 h.b. and the condensor fan started making a horrible sound "like a leaf blower" so I took it to the dealer and they replaced under warranty. about a week later the same sound came back "leaf blower" took it back to the dealer and they said the fan that they had replaced is working to spec and that it was just a "little" loud. Has anyone else had a condensor fan issue or know if soething else could cause the fan to be so loud?
Thanks all
